Product Overview

The REC670 (1MRK002814-AB) is an advanced Intelligent Electronic Device (IED) specifically designed for the comprehensive control, monitoring, and protection of substation bays. As a flagship component of the ABB Relion 670 series, the REC670 (1MRK002814-AB) is engineered to handle complex interlocking and automation sequences in medium- and high-voltage transmission and distribution networks. This unit consolidates bay-level control of circuit breakers, disconnectors, and earthing switches with high-precision measurement and synchronization capabilities. Built for the modern digital substation, it provides native support for IEC 61850, ensuring deterministic communication and seamless integration into higher-level SCADA and Substation Automation Systems (SAS).
